• Earthquake thermodynamics is formulated in terms of microscopic quantities. Basic thermodynamic relations for line defects (dislocations, linear vacancies) are derived under the assumption that a dense network of defects forms a kind of superlattice. Thermodynamic functions of line defects are associated with defects in the superlattice. With this assumption the Gibbs free energy may have a minimum corresponding to the equilibrium concentration of vacant dislocations in the superlattice. A motion of line defects forms a two-dimensional structure which seems to fit an earthquake modelling. Theoretical results for the strain, stress, magnitude, seismic moment, and an entropy jump during an earthquake process, are derived.
